Acoustic bandgap sensors for hot-spot damage monitoring
… for areas of known damage already initiated (hot-spots) in critical components of a structure. This thesis examines the proposed use of ABG materials as sensors by showing experimentally and analytically how ABG can be used to detect and quantify change in the strain field of the substrate …

Hot spot detection and protection methods for photovoltaic systems
Photovoltaic (PV) systems are becoming more prevalent as countries around the world focus on integrating renewable energy resources into their power grids. Also, there is a need for power grids to become more intelligent and adaptive. As a result, PV systems require additional functionality, such …

Mobile sensor systems for field estimation and "hot spot" identification
… pose difficulties in field estimation and "hot spot" identification from sensor data. My thesis contributions aim to bridge this gap. In this thesis, I designed and developed a mobile sensor system for urban light infrastructure monitoring and studied two problems on field estimation in the …

Investigation and characterization of single hot spot laser-plasma interactions
… by studying the interaction of a single laser hot spot, or speckle, with a preformed, quasi-homogeneous, long scale-length plasma. Recent single hot spot experiments resulted in a wealth of data and the first definitive observation of two LPIs. Namely, the Langmuir decay instability (LDI) …

Assessing Topside Thermal Solutions for Hot Spot Management of Micro-Scale Electronics
… to address a subcategory of the issue, termed "hot spots", which stems from large power densities contained within increasingly smaller electronic components. Topside chip integrated thermal solutions are proposed as an approach for thermal management of these hot spots, where carbon materials …

A numerical study of shock-induced hot spot generation in energetic material
This thesis studies the formation of hot spots in energetic materials by shock initiation. A mathematical model has been developed based on viscoplastic pore collapse mechanics. Governing equations for the condensed-phase and gas-phase dynamics are derived which contain important processes …

Tracking hot spot dynamics in solid state explosives with shock compression microscopy
… 2 ns resolution, while multi-frame, high-speed photography simultaneously captured short movies of explosive behavior with 2 µm resolution. The entire shock-pump, visible emission-probe platform, referred to as a shock compression microscope, is tabletop-based and has uniquely permitted …

Reducing the Hot Spot Effect in Wireless Sensor Networks with the Use of Mobile Data Sink
The Hot Spot effect is an issue that reduces the network lifetime considerably. The network on the field forms a tree structure in which the sink represents the root and the furthest nodes in the perimeter represent the leaves. Each node collects information from the environment and transmits data …

A Second North American Hot-spot: Pleistocene Volcanism in the Anahim Volcanic Belt, west-central British Columbia
… eastern end is interpreted as the effect of a hot-spot underlying the Interior Plateau of British Columbia. Other hypotheses for the existence of the AVB include regional extension, a plate edge/slab window effect along the northern edge of the subducted Juan de Fuca/Explorer plates, and a …

Shock convergence and mix dynamics in inertial confinement fusion
… confinement fusion (ICF). Capsule assembly and hot-spot formation require careful timing of multiple shocks to maximize hot-spot heating while minimizing heating of the main fuel. Unmitigated mixing of the main fuel with the hot-spot can quench hot-spot heating, resulting in reduced gain or …

Studies of electron heat conduction in magnetized, shock-driven implosions at OMEGA
… The electron heat conduction, one of the primary hot spot energy losses, is suppressed perpendicular to the external magnetic field, which is expected to increase yields and temperatures in collisional plasmas. However, since the particle and energy transport are restricted in one out of three …

Finite Element Modelling of Ventilated Brake Disc Hot Spotting
Hot spotting of automotive disc brakes is an undesired thermal localisation phenomenon, which is a challenge for numerical modelling in terms of both accuracy and efficiency especially for complex disc geometry. In this research, the aim was to develop a computationally efficient finite element …

Exploring the Overlap, Saliency, and Consistency of Environmental Predictors in Crime Hot Spots: A Remote Systematic Social Observation and Case-Control Examination
… characteristics, and contexts of crime hot spots are not consistently the same or generalizable across unique units of analysis and crime types. This dissertation will simultaneously integrate different types of environmental criminology predictors, including crime generators and …

Effects of Laser Frequency and Multiple Beams on Hot Electron Generation in Fast Ignition
… ∼10 kJ of energy in ∼10 ps into a small hot-spot at the periphery of the compressed core, igniting a fusion burn wave. FI promises a much higher energy gain over the conventional central hot-spot ignition scheme in which ignition is achieved through compression alone. Sufficient energy …

Free self-assembly of spontaneously chiral, supramolecular structures
… Lennard-Jones spheres, are investigated. Here, hot-spot zones on the rims of the discs are used to provide strong interactions with the spheres. Simulations of disc-only systems lead to self-assembly of multi-thread, chiral fibres. Depending on the choice of particle shape and face-face …

Targeting Traf6 For Cancer Therapeutical Development
… were carried out. Computational prediction of hot spot residues on the protein-protein interaction of TRAF6 and RANK were examined. Three methods were used: Robetta, KFC2, and HotPoint, each of which uses a different methodology to determine if a residue is a hot spot. These hot spot …

Developing an active, high-heat-flux thermal management strategy for power electronics via jumping-droplet phase-change cooling
Mitigating heat generated by hot spots inside of power electronic devices is a formidable obstacle to further increases in power density. This work presents the first demonstration of active cooling for hot spots in compact electronics via electric-field-enhanced (EFE) jumping-droplet condensation. …
